Serial No. 645,212.

the city, county, and State of New York,

have invented certain new and useful Improvements in Wrapping-Machines, of which the following is a specification.

This invention relates to wrapping machines and more especially to machines for placing a wrapper on packages of soft and plastic materials, and finally pasting a strip of paper over the closed side and ends of the wrapped package to seal same.

Means are further provided for'nianipnlating the package to present its closed side rating the strip so it may be easily torn from the package to loosen the wrapper so that it may be removed without injury to the material, and, finally, pliable rollers are provided to work against the ends of the strip to effectually seal same and paste them down upon the ends of the package: all of which are more fully described in the-following specification, set. forth in the claims and illustrated in the drawings, wherein like parts in the several views have been given the same reference numerals.

Figure 1 is a side elevation of that part of a wrapper machine embraced inthis invention. Fig. 2 is .a plan view of same.

" Fig. 3 is an end view of the machine. "Fig.

4 is a detail of same, showing some of the parts in a different posit-ion. Fig. 5 is a detail view of the mechanism for placing and pressing the sealing strip partly; insection. Fig. 6 is a sectional view of the perforating and cutting mechanism for the sealing strip.

7 Fig. 7 is a sectional view through the feeding plate, showing the mechanism for tipping the package. Fig. 8 is a similar view with the parts occupying a different position. Fig. 9 is a plan view of the tipping mechanism above referred to. Fig. 10 is a perspectiveview of a completed package.

This device is adapted to be fitted to machines already in use, and which wrap the packages above described, the portion of frame work 10 forming the rear end of this wrapping machine. As the packages are wrapped and their ends properly folded, they are received into a. passage-way 11 formed by side walls 12 and the bottom plates 13 and 14. In the intervening space between these two plates is located an angular frame having a slotted longer portion 15 and fingers 16 at right angles to the longer part 15. This frame is trunnioned in bearings 17 at each side of the passageway 11 and one of the trunnions carries an arm 18 having at its outer end a roller 19' which travels along a moving arm 20. At one end of the arm 20 is a stop 21 while at the other end is a slot 22, and as the plate 23 which feeds the packages forward, is reciprocated. the roller 19 is forced downward into the slot 22, causing it to describe an arc of forty-five degrees, and throwing the downward as shown in Fig. 8. The reverse ping frame to the position shown in Fig. 7. This tipping is done as the package is fed along and reaches this point, and is necessary because the last fold in the wrapping of the package occurs on the right hand side thereof and in the operation of this apparatus the final fold of the wrapper must be placed upward to form the top of the package to receive the sealing strip. The package having been turned on its side, it is fed forward by means of the frame while tipping, along with other packages on the plate 14. The feeding and the tipping is done by means of levers 24 and 25, operated by suitable cams on the shaft 26 and through the necessary connecting links 27 and.28. As the packages are thus fed intermittently, they at last reach a point beneath a presser 29 alternately raising or lowering and carried by arms 30, carried on a shaft 31 but loose thereon. This presser is normally forced downward by a spring 32,'which encircles the shaft, but its movement is regulated by an arm 33 secured to the shaft and operating on a pin 34. The shaft 31 is actuated by means of an arm 35 longer portion 15 of the tipping frame movement of the plate 23 returns the tiphaving on its outer end a roller 36, in the path of a cam 37 on the hub of the gear wheel 38.

The gear wheel 38 is driven bymeans of one of the rollers 42 carries a knife 44.- and is reduced as at 45 to permit of a certain amount of lost motion to the strip to prevent its following the severed portion too quickly. The lower roller is provided with a block of wood 46 or similar material for the knife to act in but the two rollers also serve to move the strip forward and they are assisted by perforating or rouletting rollers 47, having suitable cutting teeth 48, while lower rollers 49 have a groove 50 in which the teeth 48 run (see Fig. 6). The sealing strip is carried by a spool 51 at any desired point on the machine, and before the strip is cut by the knife 44, it is forced up a chute 52in which is arranged a rod 53 to prevent the strip from buckling.

At the outer end of the chute 52 is a recess 54 into which moves gripping jaws 55 and 56, adapted to grasp the outer end of the strip and draw it into place over one of the packages as best shown in Fig. 3. As the jaws move toward the chute, they are held open by means of a roller 57 at the lower end of a lever 58, which rides beneath the arm 59 of the jaw 56. When the gripper is near its final position near the chute 52, the upper end of the lever 58, which is movably held between a bent portion 60 of a bar 60, slidably mounted in the frame 62, and a roller 61 pivoted to the end of slide bar 60, is made to rock on its pivot and throw roller 57 out from under arm 59 by means of the opposite end of the slide bar 60 striking against stop 60 fixed to 63, before the frame 62, to which is pivoted lever 58, has completed its movement. The jaws 55*56 then grip thesealing strip 43 firmly by means of a spring 61 attached to the jaw 56, when the frame 62 is ready to be reversed and carry the strip to its place over a package. The gripper is carried by a frame 62 which sildes on a guide way 63, and is moved by the pitman 64, whose outer end is connected with the arm 65 on the shaft 66, the latter being operated by an arm 67 having a roller 68 and actu ated by a cam wheel 69 driven by the shaft 70. A guide-rod 71 carrying the arm and hub 72 also assists in aliningthe frame 62 and after the gripper has seized the strip,

, the arm 65 shifts the frame 62 to the other end of the guide-rods 63 and 71 so that the strip 43 is carried over the package and is in position for the presser 29 to descend and affix the strip to the package. As the lever 58 reaches the outer end ofthe guide way it is again made to rock by meansof the bent portion 60 of the slide bar 60 striking against a stop 58. When the frame 62 completes its reverse movement the roller 57 is forced beneath the arm 59, raislng the jaw 56 and releasing the sealing strip. Following this operation, the package is then advanced until it passesbeneath a plate 73,

65 carried by guide-rod 7 1 depending from a plate 75 and having heads 76 which carry these rods sufliciently high to enable thepackage to pass beneath the plate 73.

The plate 75 is carried by stems 77 which are secured together at their upper ends by means of a cross bar 78 and play through sleeves 79, supported by a bar 80 carried by uprights 81, and springs 82 surrounding the sleeves and forcing the stems 77 upward. The plate 75 has'connected with it a vertical cam plate 83 in the slot 84 of which plays a roller 85 carried by'the frame 62 and as the said frame moves with its grippers to advance the strip, the roller 85 plays in the slot 84 and forces down the plates 75 and 83, permitting the plate 73 to bear upon the pasted strip, while rollers 86 carried by levers 87 and pressed inward by means of springs 88, are brought to bear upon the outer ends of the sealing strip and force them in upon the ends of the package as shown in Fig. 3, holding together the loose ends of the wrapping paper and completing the operation. With each movement of the gripper slide, which carries the roller 85, the cam plate 83 is depressed so that the plate 73 and rollers 86 operate twice between the time that the grippers leave and I return to their normal position. With the next movement of the package it is forced upon a traveling belt 89, while the rollers 86 move upward and are forced outward by means of angle pieces 90 at the ends of the plate 73, this movement also moving the plate 73 from the package so that it may advance. The belt 89 is carried by rollers 91 which are operated from any desired source and as the packages are forced outward they pass between cylindrical brushes 92, arranged on each side of the belt, and these brushes exert a pressure upon the sealed ends of the package until they are dry and effectually held in place.

As the sealing strip is cut in order to provide a section for use on one of the packages, and as it leaves the chute 52, its sides pass beneath guide plates 93, and its under side, which is gummed, comes in contact with rollers 94 which are partly bathed in a pot 95 carrying water and receiving same from the reservoir 96through the pipe 97. This supply is automatic, and as the water is exhausted from the pot95, the admission of air to the reservoir allows the escape of more water.

shaft 41, sothat the rollers are made to move in unison and the presser 29 is provided on its under side with strips of felt 29 to bear upon the outer edges of the strip only, the latter having been moistened so as to be attachedto the package at the edges only.

As will be seen in Fig. 10, the strip is divided by means of the perforated lines 99 The rollers 94 are connected by means of a sprocket wheel 98, with the into three sections, the outer ones being moist, while the middle section is dry. This middle section is immediately over the closed end of the wrapper so that by removing this strip, which may be easily torn out, the package can be instantly opened without any unnecessary manipulation that might otherwise injure its contents.

It is obvious that the details of this invention are not necessarily confined to the exact construction as illustrated and above described, but they may be modified and otherwise arranged without departing from the essential features and scope of the invention as set forth in the following claims.

What I claim as new and desire to secure by Letters Patent is:
